/**
* simple_pjsua.c
*
* This is a very simple but fully featured SIP user agent, with the 
* following capabilities:
*  - SIP registration
*  - Making and receiving call
*  - Audio/media to sound device.
*
* Usage:
*  - To make outgoing call, start simple_pjsua with the URL of remote
*    destination to contact.
*    E.g.:
*	 simpleua sip:user@remote
*
*  - Incoming calls will automatically be answered with 200.
*
* This program will quit once it has completed a single call.
